In The Risk Agent (Putnam, 432 pp.), by Ridley Pearson, everyone gets shanghaied in Shanghai. Grace Chu, a Chinese forensic accountant who served in the Red Army, and John Knox, a wandering American war zones contractor, are hired by a private security company in Hong Kong to resolve a kidnapping. Pearson delivers a roller coaster of deceits and double crosses. It all adds up to the perfect summer read: not too heavy, not too light, and plenty of fight.

In the PBS POV documentary Up Heartbreak Hill, director Erica Scharf turns her camera mostly on two Navajo teenage track athletes, Thomas Martinez and Tamara Hardy.

Salmon Fishing in the Yemen, a charming, independent film based on the award-winning Paul Torday novel of the same name, is now available on Blu-ray and DVD from Sony Pictures Home Entertainment.

It takes Trio to tango

Play Trio Garufa's "El Rumor de Tus Tangos" and you'll either get up and dance, or more likely, wish you knew how. Trio Garufa are a US-based tango group who have tested their skills in the tango clubs of Buenos Aires. Alongside traditional tracks you'll hear a few sultry tunes, such as "Milonga Uruguaya," that wouldn't seem out of place on one of those funky Buddha Bar collections. Bottom line: Trio Garufa know their art, and with tango already such a modern music form, it doesn't need much to keep it interesting.
